Application filed January 29, 1917.

To all whom it may concern:

Be it known that 1, WILLIAM G. HALL, a citizen of the United States,residing at Spray, in the county of Rockingham, State of North Carolina,have invented certain new and useful Improvements in Chairs; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention is an improvement in chairs and has particular referenceto a bracing device therefor.

An object of the invention is the provision of a bracing device for thelegs of a chair which will effectively prevent the same from spreading,and to this end, use is made of a plurality of rods having their endssecured to the legs of the chair and their intermediate portions clampedtogether in a novel manner.

Another object is the provision of a device of this character which issimple in construction, easy to manufacture and effective in carryingout the purpose for which it is designed.

The inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which for the purpose of illustrating theinvention, is shown in the accompanying drawing, wherein Figure 1 is aperspective view of the chair showing the bracing device appliedthereto.

Fig. '2 is a top plan view of the b acing device.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4c is a perspective view of one of the bracing rods.

Referring more particularly to the accompanying drawing in which likereference characters indicate similar parts, the numeral 5 indicates achair of any construction having the usual legs 6.

The bracing device which comprises the essential feature of theinvention is shown in what is now believed to be its preferred form andcomprises a plurality of bracing rods 7, each of which is V-shaped information and provided at its ends with eyes 8 for receiv- Specificationof Letters Patent.

ing suitable fasteners whereby the rod is secured to the upper and lowerends of one of the legs of the chair. Four of these rods comprise thedevice, one for each leg of the chair, and all of said rods are arrangedso as to converge with their intermediate or bent portions 9 in abuttingrelation, the rods secured to diagonally opposite legs of the chairbeing in the same vertical plane while the other two rods are in avertical plane at right angles to the first named plane.

A clamp is employed for securing the intermdiate portions 9 of the rodstogether and preferably comprises a pair of vertically arranged plates10 having the intermediate portions of their inner opposed facesprovided with grooves 11 which cooperate to form an opening forreceiving the portions 9 of said rods. The plates 10 are so arrangedthat the vertical plane of one pair'of oppositely opposed rods is atright angles to the planes of said plates while the vertical plane ofthe other pair of rods is parallel with the planes of said plates.

The clamping plates 10 are secured together by screws 12 mounted in eachend thereof and having nuts 13 threaded thereon. From this descriptionit will be apparent that the bracing device may be readily and quicklysecured to the legs of a chair and mounted in proper position.

lVhat is claimed is:--

1. A bracing device for chairs comprising a plurality of bracing rodshaving their ends secured to the legs of the chair and theirintermediate portions arranged in juxtaposition, and vertically arrangedclamping plates having their inner opposed faces provided with groovesto form an opening for receiving said intermediate portions of the rods.certain of said rods extending at right angles to the plane of saidplates, the other rods being parallel to the planes thereof.

2. A bracing device for chairs including a plurality of substantiallyV-shaped rods having their ends secured to the legs of a chair, each rodextending inwardly at right angles to the next adjacent rod and saidrods having their intermediate portions arranged in juxtaposition, andvertically arranged clamping plates having their inner opposed Intestimony whereof, I affix my signature, faces provnled wlth grooves forformlng an m the presence of two wltnesses. opemng t0 recelve salcllntermedlate portions of the rods, certain of said rodsextend- WILLIAMG.
